FURROW-OPENING DISK.

SPECIFICATION forming part of Letters Patent No. 794,621, dated. July 11, 1905.

Application filed September 20, 1904. Serial No. 225,255.

T0 @ZZ whom, it may concern:

Be it known that I, HENRY CLAY HAM, a citizen of the United States, and a resident of Liberty, in the county of Union and State of Indiana, have invented a new and Improved Furrovv-Opening Disk, of which the following is a full, clear, and eXact description.

This invention relates to agricultural implements which comprise rotary disks in their make-up, which disks roll upon the ground as the implement advances.

While the invention is intended to be used especially in connection with furrow-openers when used in planters or seeding-machines, it should be equally useful in the construction of disk harrows and other agricultural implements employing disks for any purpose.

The object of the invention is to provide improved means for attaching the disks; and the invention consists in the construction and combination of parts, to be more fully described hereinafter and definitely set forth in the claims.

The drawings illustrate a disk attached according to my invention to a boot or hoe of a seeding-machine.

Figure 1 is a side elevation of the boot and disk. Fig. 2 is a horizontal section through the boot and disk, taken, substantially, on the line 2 2 of Fig. 1 and upon a reduced scale. Fig. 3 is a vertical section taken, substantially, upon the line 3 3 of Fig. 1. Fig. 4 is an elevation representing' a portion of the inner face of the boot, and Fig. 5 is a perspective view of the spindle of the disk.

Referring more particularly to the parts, 1 represents a boot or hoe, the upper portion Q whereof is in tubular form and adapted to conduct seed ,toward the lower extremity 3 of the boot. The tubular body 2 is formed integrally with a laterally-disposed lobe4, which lobe is formed upon its inner face With asubstantially circular recess 5. (Shown most clearly in Fig. 3.) At substantially the central point of the lobe 4 a horizontal opening 6 is formed, and at this opening the inner face of the lobe is provided with an inwardly-projecting nipple or flange 7.

Upon the inner face of the lobe 4 and in the recess 5 aforesaid a spindle 8 is attached by means of a bolt 9. The form of this spindle, as most clearly illustrated in Fig. 5, comprises a substantially conical body 10, which tapers away from the base 11, of substantially circular form. The body 10 is hollow, as shown most clearly in Fig. 5, and the inner face of the base 11 is provided with an opening 12, which opening is of such diameter as to receive nicely the aforesaid nipple 7, asindicated in Fig. 3. The inner face of the base 11 is also provided with a centrally-disposed recess 13, which is preferably of substantially circular form. This recess is for the purpose of facilitating the secure seating of the spindle upon the inner face of the lobe, as will be readily understood. The inner face of the base 11 is also provided with a recess 14, which is disposed radially, as shown, extending continuously from the outer edge of the base to the central opening 12. The bottom of this recess is concave, as indicated, and its purpose will appear more fully hereinafter.

The upper edge of the lobe 4 is formed into an oil-cup 15, and the interior thereof may be stuffed with waste 16 or a wick, the upper opening of the oil-cup being closed by a removable screw 17. The wick from the interior of4 the oil-cup 15 passes downwardly therefrom in a passage or oil-duct 18, which leads to the opening 6 aforesaid in the lobe. Directly over the position of the duct 18 the inner face of the lobe 4 is provided with a rounded elongated boss 19, (shown most clearly in Fig. 4,) the material of the said boss constituting the inner wall of the duct 18, as will be readily understood. While the presence of this boss is desirable at this point for the reason that it reinforces the material of the lobe when reduced by the duct 18, it also serves a useful function in connection with the spindle, which will now appear.l In this connection it should be stated that when assembling the parts the spindle would be applied to the inner face of the lobe 4, so that the recess 14 would receive the said boss 19. Frorn this arrangement when the bolt 9 is tightened into position the spindle is securely clamped upon the boot, and any tendency of bored, as shown, so as to receive the aforesaid spindle 8. The inner edge of the hub 21 is received in an annular groove or recess 22. which is formed upon the inner face of the base 11 of the spindle; The outer extremities of the hub and spindle are substantially flush, as shown, and the disk is retained in position by means of a cap 23, which lies over the extremity of the hub and is attached by means of the aforesaid bolt 9, the head 24 whereof lies beyond same. As illustrated, this bolt 9 passes continuously through the cap and spindle and the boot, serving at once to attach the cap and spindle. the bolt adjacent to the head 24 is preferably square, as indicated at 26, in order to prevent rotation thereof, a clamping-nut 27 seating itself upon the outer face of the boot, as shown.

In order to facilitate the passing of the lulies close to the convex face of the disk and affords means for delivering seed into the furrow formed by the disk, as will be readily understood. I

While I have described my invention as ap-- The shank ofnation, a member adapted to advance with the implement, presenting a face with an elongated boss thereupon, said member having a cup for a lubricant disposed above said boss and having a duct leading from said cup and lying under said boss, a spindle seating upon said face having a recess receiving said boss, a disk having a hub rotatably mounted upon said spindle, and a cap retaining said hub.

3. In an agricultural implement, in combination, a member adapted to advance With the implementand presenting a face with an opening thereto, an oil-cup, said member havinga duct leading therefrom to said opening, the wall of said duct projecting outwardly upon said face to form a radial boss, a spindle mounted upon said face and having a radiallydisposed recess adapted to receive said boss, a disk having a hub rotatably mounted upon leading to the rubbing face of said hub, a cap retaining said hub, and a bolt passing through said first opening and retaining said cap and said spindle upon said member.

4. In a planter, in combination,a boot adapted to conduct the seed, and presenting a lobe with an enlarged recess in the inner face thereof, an oil-cup formed at the upper edge of said lobe, said lobe having an opening therethrough, and a duct leading from said oil-cup to said opening,'the wall of said duct projecting from the face of said enlarged recess so as to form an elongated boss, the face of said recess having an inwardly -projecting nipple about said opening, a spindle seating in said enlarged recess and having a radial recess in the face thereof receiving said boss, the inner face of. said spindle also having an opening receiving said nipple, a disk having a hub rotatably mounted upon said spindle, a cap retaining the same, and a bolt passing through said cap and said member and retaining said parts.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
